Yep, the 3m striping tapes work really well. Here are a couple of pics of the double striping job I did some years ago with a lot of small radius bends. I think I figured there was somewhere around 600 feet of striping on this one. I had to lay down five rows of tape to get the two parallel stripes of black OneShot enamel. The scallops mask was outlined with the striping tape also.

Your could spin the wheels and hold a pencil against the wheel to get your two guide lines then use the 3m tape just following the pencil line.
